jumping oi the track-rail relative to the-tie-' plates and the loosening of the spikes.

Another object in viewisthe prevention of engagenient of the guard-rail by wheel treads under normal trai'iic conditions.

Other objects will appear from the following description. i i

For the accomplishment of these and other objects. I have invented a guard-rail struc ture having the following characteristics. The structure isa casting. preferably of manganese of other tough steel, comprising a guard-rail having integral therewith a plurality of tie-plates which rest upon and are spiked to the ties, said tie-plates being provided with vertical shoulders against which the outer edge of'the base of the track-rail bears, and the guard-rail being also provided with filler blocks extending toward the position of the track-rail and engaging the head of the latter from below, the base of the latter from above and also bearing outwardly against the web of the track-rail. The lower edge of the filler block conforms to the incline of the track-rail base and is spaced sutficiently above the surface of the tie-plate to permit the said base to be driven into the recess thus formed until the outer edge of the rail base will snap down into engagement with the shoulder already mentioned, thus wedging the track-rail into engagement with the guard-rail structure and preventing accidental looseness between them.

The tie-plates are provided with spike holes so placed that spikes may be driven down into the ties with their heads overlapping the base edges of the track-rail.

The tie-plates are prolonged beyond the guard-rail toward the axis of the track to properly brace the guard-rail from the inside and an inclined abutment flange integrally connects such guardrail.

I also provide anew and improved form of footguard for the ends of the guardrail. Other novel features of construction, and also 0] arrangement of parts, will'appear from the following description. it In the accompanyingdrawings, I have illustrated theibestembodiment of the principles of my invention now known to me. Fig; 1 is a plan view of the track-rail and the guard-rail structure associated there with; Fig. 2 is an end view of the same, the track-rail being in section along the line 9.. 3 is a section taken portion of the tie-plate and the Ili -ll in Fi g. 1. and Ft alone the line lill lll in Fig. 1.

' to the drawings, 1 represents liei erri g the tract-rail and 2 the cross-ties. 3 is the guard-rail which except at its ends is paralle with and spaced inwardly from the trackrail, the ends of the guard-rail being flared away from the track-rail in the usual manner. p r

Integral with the guard-rail 3 are the tieplates i which are prolonged beyond the guard-rail,outwardly to carry the track-rail and inwardly to resist the tendency of the guard-rail to upset toward the axis of the railway track. i

5 represents abutment brackets integral with the inside portion oi? the tie-plate and with the guard-rail. the plate having spike holes 6 on either side of the brackets 5 for attaching the plates to the ties.

7 represents the filler blocks, one above each of the tie-plates except the plates at wherein either end of the guard-rail, said blocks be- I ing integral with the guard-rail and the tie plates and having free ends contoured so that the track-rail 1 fits up against the block,

the latter bearing upward against the head I of the rail, outwardly against the web of the rail and downwardly against inclined upper surface of the rail base.

Between the lower edge of the tiller block 7 and the rail plate 4c is a recess 8 which conforms to the lateral taper of the side of the base of the traclerail and into which recess base may be wedged into the recesses of the tie plates until the outer edge of the said base will snap down into engagement with said ribs or shoulders, as shown best in Fig. 3.

Spike holes 10 are provided in proper location so that when spikes are driven down through the same into the tie the heads of said spikes will overlap the edges of the rail base.

It is evident that the track-rail is thus wedged into engagement wth the guard-rail structure and the latter is thus rigidly sup ported against: a tendencv to tip toward the axis of the track. It is further evident that lateral thrust exerted on the guardrail will be transferred to the track-rail without danger of ruptur ng the tie-plates.

The tops of the filler blocks are downwardly concaved as shown to prevent contact with the wheel flanges.

To prevent engagement of the guard-rail by wheels traveling normally on the trackrail, as in the case of blind drivers which have relatively hroed reads I make the tread surface of the guard-rail lower than the track rail, as shown in Figs. 2 and 3. I prefer to make the dittcrcnce in horizontal level approximate (me-eighth of an inch.

At either end of the guardrail. where it flares away from the track-rail, I provide a foot-guard to prevent the human foot from being caught between the two rails. Thus I show an incline shelf 11 rising in the direction of the convergence of the two rails and cast integral with the guard-rail, said shelf extending into close proximity with the web of the track-rail and its lower and outer end being sufiieiently spaced above the adjacent tie-plate to )rovide clearance under the shelf for the rail base.

It; is evident from the foregoing that my guard-rail structure is unusually sturdy and that itsupports the guardrail in rigid relation to the track-rail.

\Vhat I desire to claim is 1. In a guard-rail structure, the combination with the guard-rail and the transversely disposed tie-plates integral therewith, of integral filler blocks extending transversely from the guard-rail and fitting up against the under side of the. head, against the web and downwardl on the base of the trackrail. the under side oi" the tiller block forming with the tie-plates inwardly converging recesses into which the side of the base of the track-rail is wedged and a vertical shoulder on the tieplate opposed to each recess into contact with which the other side of the rail base is snapped.

2. In a guard-rail structure, the combination with the guard-rail and the transversel v disposed tieplates integral therewith, of filler blocks rites-ml with the guard-rail and extending into ctmtact with the track-rail, the lower edge of the filler block forming with the tie-plate an inwardly converging recess and the tie-plates being provided with trtmsversely disposed shoulders opposing said recess. so that the track-rail may be wenged into position with one of its base edge wedged into said recess and its other base edge wedged down into engagement; with said shoulder, and the tie-plates being prolonged toward the axis of the track and being provided with abutment flanges connecting with the guard-rail to prevent fractnde of the tie-plates.
